When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -3a - a = 5a - 8z - 3 for a in terms of z.
| 4z - 4 | |
| -\(\frac{1}{6}\)z + 1 | |
| -4z - 4 | |
| \(\frac{7}{8}\)z + \(\frac{3}{8}\) |
